I am a complete newbie as I've started this year, but I believe the brown spots and the holes are sawfly caterpillars. If you look under the leaves, often there are little green "caterpillars". My roses look alot like yours....I dunno about solution yet unless a hard water spray but on the underside to knock them off or systemic poison that could kill them when eating leaves but...I haven't gotten around to that yet. I don't have a problem with pesticides but I do try to use them as a last resort. If I'm wrong, I really hope someone corrects me! Hope this helps.

yes, you're right about them being sawfly larvae. :) :)

I tend to turn the leaf over and look for the larvae...when I find it...I just fold the leaf over on itself and squish it between the leaf.

I will say that when growing bands or young roses, you feel so happy to see new foliage and then sawflies or whiteflies (I think this is my current pest issue with my new bands) ruining the beautiful new foliage is so sad that I can see why people use pesticides. I did a brief search and I guess yellow cards/cups coated with petroleum may help so I'll try that first. It's so disheartening....

Thanks for the tips @kw and @rosecanadian! I looked this morning and you’re right! So many caterpillars :(
I’ll try the cards/cups with petroleum first! We have so many butterflies in the yard I’m reluctant to try pesticides

Are you, or are you not, trying to do away with butterfly progeny (caterpillars)?

If so, why?

My reference is Alice in Wonderland. Typically read in one’s formative years.

Ah, I think what we're talking about are sawfly larvae which I am calling caterpillars because they kind of look like one. I'm pretty sure they are not butterfly caterpillars (at least mine, and I"m pretty sure gina's as well), since I googled what sawfly larvae look like. And unlike Gina, I get very little butterflies (so far! But my garden is new to me this year)
